Passion fruit is a tropical fruit from the Passiflora vine, known for its tart, aromatic, jelly-like pulp filled with seeds, encased in a tough, purple or yellow rind, rich in antioxidants, fiber, and vitamins, excellent for fresh eating, juices, desserts, and salads. Ripe ones are often wrinkly and heavy, and it's enjoyed worldwide for its vibrant flavor, supporting health like blood sugar and heart function.
